I am running the mmwave demo through CCS using the development mode. So I flashed the ccsdebug binary, compiled the project in CCS, and loaded the MSS and DSS binaries into the respective cores before running them. I have been able to get the demo to run this way, and it shows plots in the web visualizer. However, after some time of running (a couple minutes), the plots in the GUI will stop updating, and there are errors in CCS. The first error is always the following:
IcePick_M_0: Error: (Error -261 @ 0xFFFFFEFB) Invalid response was received from the XDS110. (Emulation package 7.0.100.0)
Other errors follow, but I think they're all related to this.
Before, I was seeing this problem much sooner, within seconds after running the demo, or even while trying to connect to the cores for the first time. I then made sure the negative power connection to the board was grounded, and that improved things to the point that I could run the demo for a short time. Before, when the negative was not grounded, perhaps there was a ground loop causing issues with the debug probe. However, the problem is still there, just happening less often.
What further steps should I take to troubleshoot this?
